摘　　要：对PCI总线技术进行了改进,改进后的PCI-E除具有原有总线技术的特点外还具有一些新的特点:串行差分接口;传输速率达到了2.5 GT/s;具有多种传输模式;高级RAS,支持热插拔。PCI和PCI Express相比保留了PCI的Load-Store架构技术等。PCI Express采用串行的机制,PCI-Express较之PCI也更加灵活,比如支持多种传输速率;PCIExpress支持更多更先进的技术,比如支持RAS和热插拔。此外,它还有个很大的优点,与PCI软件100%兼容。In this paper,PCI bus technology has been improved,which has some new features besides some PCI-E characteristics of the original external bus technology,a serial differential interface;transfer rate achieved 2.5GT/S;with multiple transmission modes,advanced RAS,hot-swappable.The PCI Express retains the PCI-Load-Store architecture technology compared to PCI.PCI Express uses serial mechanism,Which is also more flexible than PCI,for example to support multiple transmission rates,PCI Express support for more advanced technologies,such as RAS and hot plug support.In addition,it also has a big advantage of the software 100% compatible with PCI.
